The Multilateral Trading System:

GATT trade rounds were getting longer and more complicated. In the sixth,
the Kennedy Round, participation surged to more than 60 countries - 66
nations attended the opening ceremony, pictured here, on 4 May 1964 in
Geneva.

The subjects discussed also expanded, from the traditional tariff cuts
to new trade rules, such as those on the use of anti-dumping measures.

The Kennedy Round was named after the US president who had died the
previous year. This was partly in his memory and partly because President
Kennedy had secured the 1962 US Trade Expansion Act which authorized the
US government to negotiate tariff cuts of up to 50%, a key factor allowing
the talks to take place.
